Hackers in Miami targeted an electric billboard placing the slogan “No Latinos No Tacos” on a flashing construction sign on a major roadway in south Florida.

The sign was supposed to be displaying a message warning drivers that the coming exit was closed to traffic.

Officials attempted to change the text on the sign back to its intended message, but were unable to do so and were forced to simply turn off the sign. They said the signs are password protected, but that generally does little to stop hackers intent on changing them.
